Lining journal-boxes



UNITED STATES PATENT OFFICE.

JOSEPH CORDUAN, OF BROOKLYN, NFV YORK.

LINING JOURNAL-BOXES.

Specification of Letters Patent No. 31,655, dated March 12, 1861.

To all whom 'it may concern.'

Be it known that I, JOSEPH OORDUAN, of the city of Brooklyn, county of Kings, State of New York, have discovered a new and Improved Lining for Journal Boxes and Slides; and I do hereby declare that the following is a full and exact description of my invention, reference being had to the accompanying drawings and letters marked thereon. 4

The nature of my invention consists in lining ournal boxes with horn.

To enable others skilled in the arts to make and use my invention I will describe its construction.

I boil a piece of horn of the desired shape in oil and water until it becomes soft and pliable, in which state I place it on the journal box to be lined and using` a follower press the horn A into its place.

The journal box B as shown in Figures l and 2 of the drawings having a recess C cut into lit retains the horn in its proper position.

The advantages in lining journal boxes with horn, instead of glass, wood or paper pulp, which have been heretofore used, are very essential.

I have tried experiments and had a ournal box lined with horn run on a locomotive on the Hudson River Railroad; it ran eight thousand miles before it was removed and during that time it was not even heated. I have also one of my journal boxes running upon a Toodworth planing machine at a speed of thirty live hundred revolutions a minute without its being at all affected by heat, which is the irst and greatest desideratum in journal boxes. In some respects paper pulp may be as good as horn7 but the former is from its nature liable to be worn out sooner than horn. Glass is liable to break.

I do not claim the broad idea of lining journal boxes-but IVhat I do claim as my invention and desire to secure by Letters Patent is- The lining of a metallic journal box with horn, substantially in the manner described.
